From the Guidelines
The treatment for rectal itchiness should start with improved hygiene and lifestyle modifications, and may include over-the-counter or prescription medications, with the most recent evidence suggesting that topical mesalamine can be effective for proctitis, a condition that may cause rectal itchiness. When considering treatment options, it's essential to identify the underlying cause of rectal itchiness, as it can be caused by various conditions such as hemorrhoids, pinworms, skin conditions, or more serious issues. Some key considerations for treatment include:
- Improved hygiene: gently cleaning the anal area with unscented, alcohol-free wipes or plain water after bowel movements, followed by patting dry rather than rubbing 1
- Lifestyle modifications: wearing loose cotton underwear, avoiding irritating foods like spicy foods, caffeine, and alcohol, using unscented toilet paper, and avoiding scratching
- Over-the-counter options: hydrocortisone cream (0.5-1%) applied sparingly to the affected area up to twice daily for no more than 1-2 weeks to reduce inflammation, zinc oxide creams or petroleum jelly to create a protective barrier
- Prescription medications: stronger corticosteroids or antifungal creams if a fungal infection is present It's also important to note that if symptoms persist beyond two weeks, worsen, or are accompanied by bleeding or severe pain, medical evaluation is necessary to rule out more serious conditions. In the context of proctitis, topical mesalamine is the first-line therapy, with a pooled odds ratio of 8.3 for symptomatic remission, 5.3 for endoscopic remission, and 6.3 for histological remission 1. However, the treatment for rectal itchiness should be individualized based on the underlying cause and severity of symptoms, and patients should consult with a healthcare professional for personalized advice.
